TO ALL WHOM IT MAYCONCERN:

De it known that I, WILLIAM B. COATES, of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an Improved Stove; and I hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in whichi I Figure 1 represents a front view of the stove, with its self-acting ash-sitter below.

Figure 2 is a vertical section of the stove.

Figure 3 represents a side elevation of same.

Figure 4 represents a cross-section of, the ash-sifter.

Figure 5 represents a top view of the convex-shaped grate.

Figure 6 represents a side view of the grate, with its shaker and the lower plate in which it revolves.

Figure 7 represents an under side view of the stove and grate-plate, with their flanges, and apertures for discharging the ashes.

The nature of my invention consists in the construction of the stove, with its ribbed conical top, its doors sliding on each side of the stove, and a convexshaped grate, with flange, operating on the inside of the flanges of the bed-plate of the stove, vibrated by a peculiarly-shaped shaker.

Underneath the bottom of the stove is a self-acting sifter, that is located in the cellar or under the door of the fireplace upon which the stove stands, the sifter having discharge-pipes at its end, the coarse ashes falling through theV front one, and the dust through the under one. i

A t the rear part, and outside of the stove, isA attached a receptacle for water, with two upright pipes, one

' having a swivel top, through which the water is poured into the receptacle, the other to carry olf the steam into the fines. i i

. The stove has a double-jointed pipe, leadinginto the 'lower side of an oval-shaped drum, with a pipe at the top to carry oil' the smoke, into the chimney. i

Fig. 1 represents the front of the upright stove, with a- {ire-board, A, surrounding it, that is used when r the stove is set vinto afireplace.,

l B is the ribbed coical'top of 'the' stove,is monde of cast iron, and tittediupon the Vtop/C, .of the body of the stove. t

D D are the sliding doors, that slide from iront to the back, around the body of the stove, and, when lopen, leave one-half of the stove open, sons to form an operi grate. The top edge of each door D is angular, and operates in an angular groove in the lower edge of the body C of the stove. The lower edges of Vthe doors D D have angular grooves resting upon the sharp edge, andoperating onthc cylinder E below, so as to4 enable the doors to work freely, and not be choked up by ashes collectingon the edges of the cylinder. The front 0f v one door D has a refunding bead on the outer edge, to make a close joint when thedoors are closed.

F represents the'handle ot the shaker, that passes through the cylinder of the stove, and has an elbow or l arm, G, extending downwards, with a round knob at its lower end, that catches into the front part of the rim H of the gra-te I, by which means the grate is vibrated back and forwards.

` .The rim H (on which the convex grate I lrests and operates) fits upon the lower bed-plated, and has a t ange, K, on its lower side, that revolves on the inner side of a iiange, L, on'the bed-plate J of the stove.

The bed-plate J has semicircular apertures, M, through which the ashes are discharged into the funnel 1N beneath, that conducts the ashes to the inclined sifter O, that has a grate, P, through its centre, by means of which the coarse ashes or coal are carried o through the spout Q, and the dust, as the ashes pass through the sifter O, falls through the grate P, and passes down through a spout into receptacle R, by which means the ashes are thoroughly sifted, and the sifter O, being covered with a sliding lid, prevents the dust from escaping or being scattered about while it is passingdown into the receptacle R,whilst the coarse ashes continually pass down the upper sideot the grate P, (on account of the momentum of the fall at the upper end, and the inclination of the grate.) The coal is all saved and collected Without making dust orV dirt, as is usually the case with other sifting-machines. v

S is e draught-pipe under the Hoor, through which'co'ldvair may be passed up into the stove. T is a receptaele for water at the iower side of the stove, with two upright pipes, U-U, for the purpose of distributing moisture or steam through the room or upper flues.

The front pipe U has a swivel-neck nndvstopper et the top, through which` Wetercan be introduced at any time to ll the reservoir-,for (when necessary) discharges moisture into the-room by removing the stopper at the top. l Y i 1 I' A The smoke `posses ofi' from the stove through the double-jointed pipe V, that is connected et the lower side of a drum or heater, W, and passes ofi' through smoke-pipe X, thereby increasing the draught more than is usual with ordinary heaters.

l The body of the stove C, at Y, rests in an ofiset or shoulder on the top of the cylinder E, as shown in fig.

2., the inside of the cylinder E being convex at the centre, and thicker than at the top or bottom, thereby preventing the cylinder from burning out as soon as it would otherwise do, and having feet, Z, on each side et the bottom, for fastening the cylinder to the hed-plate.

What I claim es my invention, :md desire to secure by Letters Patent, is-

1. The combina-tion of the vibrating-rim H, with its ange K, and the bed-plete J, with its flange L and /a-pertures M, the shaker F, with its arm Gr and knob, as herein described und for the purposes set forth.

2. The construction of the Vbody of the stove, when combined with the cylinder E, shoulder Y, and ribbed top B, es herein described.

3. In combination with' the foregoing the sitter O, with funnel-shaped top, N, grate P, spout g, and receptacle R, when constructed and operating as herein described and for the purpose set forth.
